"I always say that every person on this earth has the freedom to practice or not practice religion. It is all right to do either. But once you accept religion, it is extremely important to be able to focus your mind on it and sincerely practice the teachings in your daily life. All of us can see that we tend to indulge in religious favouritism by saying, "I belong to this or that religion", rather than making effort to control our agitated minds. This misuse of religion, due to our disturbed minds, also sometimes creates problems.
I know a physicist from Chile who told me that it is not appropriate for a scientist to be biased towards science because of his love and passion for it. I am a Buddhist practitioner and have a lot of faith and respect in the teachings of the Buddha. However, if I mix up my love for and attachment to Buddhism, then my mind shall be biased towards it. A biased mind, which never sees the complete picture, cannot grasp the reality. And any action that results from such a state of mind will not be in tune with reality. As such it causes a lot of problems. "
